Application filed. July 18,

This invention relates to that type of cam used in looms to operate thepicker-stick. These cams are used in pairs, one atthe right side of themachine and the other at the left side of the machine, and thepickpoints have their working surfaces inclined in opposite directionsfor proper engagement with the pick-ball. These cams wear outpick-points quite rapidly and for that reason the pick-points arecommonly made detachable, for ready renewal. The necessity of makingthese cams rights and lefts of course requires that the pick-pointsshall be rights and lofts also, and this means that the textile millsmust carry in stock a large number of both right and left cams andpiclcpoints.

It is the object of the present invention to provide a cam adapted toreceive either a right-hand pick-point or a'left-hand p1ckpoint, thusrendering it unnecessary for a mill to carry in stock more than one typeof cam, and, of course, also rendering it unnecessary for the loom-fixerto carefully select the proper cam when he replaces a worn cam'by a newone. This obviously will result in a considerable economy to the mills.

Referring to the annexed drawing by reference numerals, 10 designatesthe body of the cam, which, as usual, is provided with a removablesection 11 for convenience in applying it to the cam-shaft. This cam isof the usual shape so far as outline is concerned. The pick-point isalso the usual shape so far as the cam surface is concerned.

In the drawing, 12 designates a right-hand jpick-point and 12' aleft-hand pick-point.

These pick-points are of the usual form, consisting of the cam-face 13and the bodyflange 14 provided with a bolt-hole to en-- able it to beclamped to the cam by means of a bolt 15.' a

The cam-bodyis provided with-a double socket to adapt the cam to receiveeither a right-hand pick-point or a left-hand pickpoint. flange 16formed centrally of the foam-body, i. e,, midway between the oppositefaces of the cain-body. Radial shoulders .17. are

' provided on the body of the cam to receive This double socket isformed of a against the central web. The face flange 13 of thepick-point has its ends in abutting relation with the ends of the flange19 of the cam-body, the surfaces of the flange of the cam and of thepoint being, of course, flush at the joints to permit the pick-ball toroll off the flange 19 onto the flange 18 with the least possible clickor jar, The

face of the pick-point is, as usual, inclined.v

or bevelled toward one side to properly receive the pick-ball, theincline on the right pick-point being opposite to that of the leftpick-point. The surface of the body-flange 19 is slightly inclined inopposite directions from a center point, to provide virtually two camsurfaces 19', so that, whether a right pick-point or a left pick-pointbe attached to the cam-body, the cam of the cam-body will present a camsurface that will coincide in inclination with the inclined surface ofthe pick-point.

What I claim as new is:

1. A double loom-cam provided with a double socket adapted to receive,either a' right pick-point or a left pick-point.

2. A loom-cam provided with a double socket adapted to receive either aright pick-point or a left pick-point, said double socket consisting ofa central web and a pair of radial shoulders at each side of saidcentral web, said central web being provided with a bolt-hole.

8. A loom-cam having its working-face inclined in opposite directions toprovide tWo bevelled Working surfaces, this cam being provided With adouble socket at its pick-point, one socket at either side of theGain-body, whereby either a right-hand pick-point or a left-handpick-point may be secured to the ca m-body in one of said sockets. Y

4. A 100m cam having its working face inclined in opposite directions toprovide tWo bevelled Working surfaces around its periphery except at onepoint, the cam at this point being provided with holding means adaptedto receive either a' righthand pick-point or a left-hand pick-point,

In testimonyv whereof I hereunto alii'X my signature.
